COMBINED'ROTATING AND RECIPROCABLE TOOL.

To all whom it may concern:

Be it known that we,'CARL ALFRED GUS- TAVSON and HENRY C. KARLsoN, citizens of the United States, and residents, respectively, of the borough ofjBrooklymin the county of Kings and State of New York, and of Hasbrouck Heights, in the county of Bergen and State of New Jersey, have invented certain new and useful I1nprovements in a CombinedRotating and Reciprocable Tool, of which the following is a speci fication.

This invention relates to a combined rotating and reciprocating tool. I

is imparted to the said slide by means of a lug 26, that enters a suitable recess in the projection 25. The said lug is in threaded engagement with the screw 27 that is maintained in position in the slide 21.

The said slide 21 has formed at the lower portion thereof a ledge 28, which is utilized for propping up the object or work by means of blocks and wedges when centering the same. The slide 22 has a suitably dovetailed recess 22 which is in engagement with acorresponding' dovetailed member 29, formed integral with the side walls of the said headstand. The latter is hollow and is entered by the lug 23, which is threaded internally to receive the screw 24. The bearings for the said screw 24 are placed to keep it in an upright position, with its upper end Drojecting above the head-stand and with the lower end thereof entering a pocket30 formed in the bottom of the said stand 17. The lower, end of the screw 24 is provided with a retaining nut 24. The slide 22 is locked by the screw 24 except when motion 1s imparted to the same by the gearing hereinafter mentioned. I

The base-stand 18, Figs. 1, 2 and 5, is flanged at the bottom thereof and is bolted to the table 16. .The latter stand contains means for supporting and rotating the end of the work, in proper relation to the head supporting and adjusting stand. The latter means comprise a supporting center screw 31, a face plate 32, a dog 33 and gearmg connected therewith. The. supporting center screw 31 has its threaded portion in engagement with the base-stand 18, and its tip end supports the work or ob ect (Flg. 2). The face plate 32 has extending therefrom a spindle 34 which is journaled in the basestand 18. The spindle 34 is traversedby the supporting screw 31, the latter belng dle and it is locked, in position, by means of a jam-nut 35. The dog 33 when used on a in threaded engagement with the said spinsquare base as shown, comprises a pair of flat bars which are joined by cross rods 36. Nuts 37 tighten the bars in place, Figs. 2 and 3. When the dog is used on a round base, the clamping members are suitably curved. The said dog 33 is adapted to be engaged by two or more fingers 38, projecting from the face-plate, and a flexible connection is hereby provided between the face-plate and the end of the work clamped by the dog The said connection rotates the work when the axis is in line or at an angle thereto.

A cutting tool 39 is provided for cutting grooves in the surface of the work. The said cutting tool is clamped in a block 40, that is secured to a tool-carrier 42, which is mounted on a cross-rail 44, transversely mounted on the uprights 45. A. screw 46 moves the toolcarrier 40 along the crossrail 44 to shift the tool laterally. This construction is suitable for a planer provided with said improvement; for a milling-machine embodying like improvements, a rotary cutter would be employed. instead of the stationary tool 39.

Motion is imparted to the elevating and to the work-rotating mechanism, by means of a shuttle-shaped shoe 48, Figs. 6, 7 and 8, that is actuated by the reciprocation of the table 16. The said shoe 48 is lodged in an adjustablegroove 49, which is laid out in the collar guide bar 50. The said guide bar is composed of collars 50 which are mounted on a rod 51. The adjoining sides of the said collars are formed with teeth or serrations 52, which upon being pressed and clamped together engage with one another and become interlocked, constituting one rigid bar with said rod 51. The collar guide bar 50 is located alongside the bed 15 of the machine. In the construction represented in Figs. 1 and 2, the said collar guide bar and the rod thereof are held horizontally at the side of the bed 15, below the reciprocating table 16, by depending brackets 53, and are maintained in position by means of set-screws 51 The groove 49 is formed by the registration of the notches in the faces of the collars 50 The serrations on the opposite sides of the collars permit the said notches to be off-set at various distances from one another so that the notches will form one continuous groove or pathway. The curvature of said groove by reason of the means of variably locating each collar can be made to assume any desirable direction. The shoes 48 engaged in the said groove are carried in the hub extensions 56 of the beveled- gears 54 and 55. The said hub extensions are revolubly mounted in brackets 57 that are secured to the head and base-stands respectively 17 and 18. Each of the said shoes has a cylindrical shank 58 which pivotally engages a correspondingly .to the side of the base-stand 18.

shaped hole 59 in the hub extension of the respective gears 54 or 55. The heads of the said shoes are pointed at both ends 60 and 61 and pass successively through the said notches in both directions. The beveled gears 54 and 55 are caused to rotate in one direction or in a direction opposite thereto when the table is reciprocated, and will turn more or less rapidly in proportion to sinuosity of the groove 49. The bevel gear 54 meshes wit-h a gear 62 that is secured to the lower end of a vertical shaft 63 which is journaled in the brackets 64, 65, that project outwardly from the said head-stand 17. The shaft 63 carries at its upper end a gear 66 which is in engagement with a pinion 67 that is rotatably mounted on a stud 68, and the said stud is secured in a slotted arm 69. A large gear wheel is similarly mounted on the said stud 68 and is suitably arranged to rotate with the pinion 67, the said gear 70 meshes with a pinion 71 that is secured to the upper end of the screw 24 that is in threaded engagement with the lug 23 on the slide 22. The coacting parts connected with the slide 22 have been previously described. The rotary motion of the gear 54, is caused by the action of the groove 49 on the shoe 48 consequent to the reciprocation of the table 16. The said rotation of the gear 54 is transmitted to the above referred to train of gears and the raising and lowering of the end of the work adjacent to the head-stand 17 is governed by the curvature of the groove and the relation of the gears in the said train. The slot in the arm 69 provides for the shifting and adjustment of the stud 68, to accommodate various combinations of gears, as may be required by the diameter of the object operated upon, or the pitch of the groove traced therein, or the speed with which it is desired to turn out the work. The bevel-gear 55 gears with a gear 72 which latter is secured on the lower end of an upright shaft 7 3, that is journaled in the brackets 74, 75, extending outwardly from the base-stand 18. At the upper end of the shaft 73 is fastened a gear 76, the teeth of which mesh with the teeth of a pinion 77, that is journaled on the upper end of a stud 78, secured in a slotted arm 79, similar to the arm 60 and provided for a like purpose. On the stud 78 is also journaled a gear 80, which is locked with the pinion 77. The teeth of gear 80 mesh with the teeth of a pinion 81, that is secured to the upper end of a vertical shaft 82, that carries a worm 83. The said shaft 82 is journaled in a bracket 84 which is attached The worm 83 engages a worm-wheel 85 that is loosely mounted on the aforesaid spindle 34, and confined between the rear end of said basestand and a ratchet-wheel 86, that is rigidly secured to the spindle 34. Spring-pressed pawls 87 and 88 are pivoted to the outer side of said worm-wheeland are reversibly engaged with opposite sides of said ratchetwheel. The latter transmit motion from the worm-wheel 88 to the ratchet wheel 86 in a predetermined direction. Another ratchetwheel 89, is secured to the spindle 34, at the end thereof adjoining the face-plate 32. The ratchet-wheel 89 is engaged by a re versible pawl 90, pivotally attached to an ear 90 formed in the upper portion of the base-stand 18 and adjusted to slide over the teeth of its coacting ratchet'wheel 89. The nature of the operation of the pawls is such that the rear pawls 87 and 88 always work together in one direction or the other, according to which way they are turned, and the forward pawl 90 is set likewise to check back rotation. The train of gears 76, 77, 80 and 81 rotate with the bevel gear 55 and through the interposed element's rotate the face plate 32 which rotates the work or object operated upon with the spindle 34, also the dog 33 and the end of the work on which it is clamped, in the same ratio and with a predetermined velocity of rotation dependent upon the sinuosity of the groove 49 in the collar guide bar 50. The said reversible pawls 87 and 88 enable the operator to cause the work to rotate in the direction desired, so that the said work 19, can be grooved or fluted in either direction.

The trains of gears 76, 77, 80 and 81 comprising the actuating mechanism for the stands 17 and 18 can be varied to suit the raising, lowering and turning of the work, and the rooves traced thereon, as well as by changing the pitch of the groove in the said collar guide bar 50. The face-plate 32, spindle 34 and their appurtenances are locked by the worm 83 except when motion is imparted to the latter by means of the 7 said train of gears.

The modification illustrated in Figs. 9 to 12, inclusive, relates to the employment of means equivalent to those hereinbefore described for raising and lowering and for rotating the work. Partsof the machine not here specifically referred to,-are identical with the parts already described, and therefore are designated by the same nu merals. In the modification the guide bar 50 is mounted above instead of below the reciprocating table 16. In mounting the guide bar 50 above the table 16, brackets 91 are used, which are bolted to the side of the bed 15, and extend the requisite distance above the said table. By mounting the guide bar 50 above the table a simple arrangement of spur-gears is obtained in place ofthe more elaborate gearingshown in the construction above. Spur- wheels 92 and 93 replace the bevel- gears 54, 62 and 72 on the hubs 56. The spur-gear 92 meshes with a larger spur-gear 94 which is mounted on a stud 95 that is secured in a lug 95 formed on the side of the head-stand 17. The said spur-gear 94'is in gear with a similar spurgear 96 that is secured to the outer end of a horizontal shaft 97, which latter is journaled in the head-stand 17 and carries an eccentric 98 on the inner end thereof. The said eccentric is fitted in a block 99, slidingly mounted between the ledges 99 and 99 projecting inwardly from the vertical slide 22 and operates the said slide and there-with connected parts. The spur-gear 93 is made to engage a larger spur-gear 100 which is mounted on a stud 101 that is secured on a lug 101 formed on the side of the base-stand 18. The said gear 18 meshes with a similar spur-gear 102 journaled on the outer end ofthe spindle 34 of the faceplate 32, which, as before described, is provided with the fingers 38, adapted to slidably engage the dog 33 that is clamped to the base of the column 19.
